🐞 Bug Report: Critical Error Updating Plugins With FAIR Plugin Active #452
Description
With FAIR plugin 1.2.2 installed on a public WordPress site all plugin updates are now failing. Deactivating the FAIR 1.2.2 plugin stopped the errors.
Detailed Description
FAIR 1.2.2 is installed and active.
Several other plugins are installed and active. Everything appears to be working normally on the site.
Trying to upload a new plugin file (zip file) to upgrade a private paid plugin to a newer version crashes with a critical PHP error. This also happened with ALL plugins deleted and trying to replace FAIR 1.2.2 with a downloaded FAIR 1.3 RC 4 zip file.
Steps to Reproduce
- Install and activate FAIR 1.2.2
- Download FAIR 1.3 RC4 zip file
- Try to replace/activate the updated plugin
